2012 Ferrari 599XX Evo suspension bottoming out

[Migz - DH]

I've spent far too many hours trying to keep my 999 rated 2012 Ferrari 599XX Evoluzione's suspension from bottoming out after around 240mph. My best M68 speed trap score is only 293.2 mph. :-/

Does anyone out there know why its suspension bottoms out so easily? How common is this behavior among Forza cars above 240 mph?

I would like to learn why this car is so unusual rather than just search through other people's tunes to find one that doesn't bottom out.

Thanks!

did you use a tune made by another player?

Do not upgrade to rally suspension, that is the cause for the bottoming out (stock is stiffer and better in many regards for this car).

Although a few tunes did exploit this bottoming out in order to make the car go faster than normally possible (above 460 km/h)

How does having the car grind on the ground make the virtual cars go faster? If that's an exploit, then what is the legitimate high speed for these cars?

I can get my tunes to 293-294 mph (471.5-473.1 kph) with rally and 290-291 mph (466.7-468.3 kph) with stock. No grinding on the ground required. And, they're completely driveable, not just rockets with wheels. :-) Maybe I shouldn't feel as bad about this as I have.

I'm able to keep the car from grinding on the road with both suspensions, but I can't keep the suspension from bottoming out with either stock or rally suspensions. (Suspension bottoming out indicated by the telemetry screen and accompanied by the thumping sound.)

First off, remove the Rally shocks, you do not need them, and they are, from my tuning experience, the main culprit of butt-grinding. I don't know how the 5 start tunes you see everyone downloading DO that without performance loss from the dragging.

Maximize spring stiffness and minimize rebound. Turn the knobs all the way to the ends. Turn your suspension into a brick. Its gonna shake but you'll stay above the pavement. It also some how gains you MPH

My personal tune goes 302.6 mph on the northbound, it wasn't until i tried the rally suspension that I found out thats whats causing the epidemic of people's cars embedding themselves into the pavement. Toyed with it a bit and managed to make the entire car sink into the world at high speed, of course totally uncontrollable.

Nice. I haven't gotten that high yet. Can you control it under other situations, or is it just basically a rocket on wheels?

So, with the normal suspension, you have been able to keep the car's wheels from thumping as they reach the upper travel suspension maximum?

Yeah with the normal suspension it does not bottom out as easily, as long as the ride height is not set as low as possible (mine is about middle possible ride height). Never had bottoming out with mine even around the normal top speeds.

As for why bottoming out can make the car go faster.... I have no clue but it has been a weird bug that was exploited for the stunts by some. Mostly for straight lines though as the handling suffers severely with the grinding of the car.. Forza devs and their programming ya know

I spent a good deal tuning and testing and it actually corners like a dream at 300 despite the aero being all the way to speed, it can weave traffic as fast as your brain can process it and take the bend without losing the lane, unlike most people I see with those downloaded 5 star tunes. The caveat is it rattles like mad at those high speeds with a rock hard suspension; I've tried loosening it up a bit and it actually loses top speed so every little thing adds up with this car.
Looking back I would have download a speed tune but I wanted control of my rim design and to be able to put snow tires on it in winter so over the course of like several months to a year I'd twiddle with the controls a little bit each time, gaining phantom speed somehow.
In the end I gained a deep understanding of tuning in this game.

Rattle indeed. Hood bouncing up and down making viewing from inside nearly impossible? If so, sounds familiar. lol What does the suspension telemetry say when you drive it?

I'll have a go at tweaking my tune after I do more Spring stuff. I'll try out setting a very stiff suspension and see if I can use you guys' info to improve it.

[Migz - DH]

With your advice, I tweaked my normal suspension build to get over 300 mph northbound and just got 295.32 mph at the M68 Speed Trap (vs 290-291 mph previously). So, a definite improvement. The suspension still bottoms out sometimes, but I barely notice it, so that's good too. :-)

I don't get it either, as if the tune sets were someones intellectual property so they locked the settings just so you cant see them.

Err....

Err what? I have the same Ferrari and it does the same thing rear wheels under the road spitting sparkles but that doesn't stop it from hitting 500 km/h, I'm just curious about the settings

Ah, ok.
In text, what you wrote previously could come off as being sarcastic. :-)

Oh no no, never meant it that way

[Migz - DH]

i can't reach 500 kph northbound on M68. I am currently stuck at 482 kph. It's not bad though. I ended up backing off of some of the extremes to try to make the ride nice and have good acceleration.

If you all are curious how it drives, look up "300MPH 5 SPEED" by Mirandir. Share Code: 106 454 988. If you want later, I can write up what I did with it.

Its funny how this car can beat even Koenigsegg Jesko. Even Mossler MT900S is faster with the right tune.
